DELAWARE METHOD AND DEVICE FOR APPLYING- OIL OR OTHER LIQUID '.l'.'O THREAD Application filed July '2,

This invention relates to devices for apuid to a thread of rayon or other material w iile the same is being wound on a spool or other support.

In winding a thread of rayon or other fibrous material on a spool or other support to form a package or roll ready for the market it is necessary for certain purposes to add a quantity of oil to the thread. In oiling devices as heretofore constructed, a definite quantit of oil was supplied to the thread said oi being picked up by the thread as itpassed to the spool or other support. Since the spool or support in machines of this kind was rotated at a definite speed of rotation during the entire winding operation, it was obvious, that, as the quantity of thread on the support built, up and increased the diameter of the package or mass, the speed of the thread increased proportionately. In oiling devices heretofore used, an increased quantity of oil was not successfully supplied to the thread when the same moved at a higher rate of s eed. This resulted in an unequal oiling o the thread, the inner portions of the ackage receiving a greater outer portions thereof.

An object of this invention is to provide a device of this kind in which the diameter of the mass of thread on the s 001 or support is used to guide the threa into different relations to the thread wiping member, whereby the oil or other liquid is applied to a longer stretch of the thread as the speed of the thread increases. Another object of improve the construction of devices of this kind in other respects hereinafter specified.

These supports, cores or spools are commonly made of pa er and conical or c lindrical in shape to aclhpt the same to rea ily cooperate with knitting and weaving machines. The reference character Y represents the thread of rayon or other fibrous material which is being wound from a spool Z.

T e machine is provided q with any usual or suitable mechanism for moving the lengthwise of the support or core X to form a substantial frusto-conical mass or package of thread thereon. In the drawings I have illustrated a portion 15 of the thread guide mechanism commonly used in connection with machines. of this kind. This thread guide mechanism is mounted on port 16 which is pivoted at 17 to the frame member 11, and includes a transverse frame counterweight 18 for holding the mechanism 15 inengagement with the outer face of the mass or bod of thread on the support or s 001 X. The thread passes from a supply rum or spool Z through suitable thread guide devices 20 and 21 o usual con struction arranged on an oil trough or reservoir 12, see Fi 2 and 3, the thread guide 21 bein in t e form of a pulley. The thread t en passes through a guide 22, arranged above the oil reservoir, from which the thread" passes through the tension device indicated generally by the reference numeral 24, and which is also of usual conthe necessary tension to the thread to ena e the same to NEW YORK,'A88IGNOB, BY HESNE ASSIGNMENTS, N.

the excess oil mittently,

winding machines part of this of the thread prefertakes place interfrom the oiled portions of the threadwhich was oiled by the wiper is thereby deposited on the various tensions and guide members.

The portion of the thread contact with the wiper these members so that a form oiling of the accordance -with which does not receives oil from substantially unithread takes place. In my improved device, the

length of contact or intervals of'time during which oil or liquid thread is increased as is applied to the the speed of. the

thread increases with the result that after enga ing the various guides and tension mem er approximately the same quantity of oil is applied toany given length of thread at all times during a number of used, the one invention including the winding of the L thread. In order to accomplish this result, different mechanisms may be shown in the drawings by way of an example embodying one form of my a rotary oiling or wiper member 30, one of these members bein employed in connection 'This rotary member may necessarily,

be substantially with each threa preferably, but not S-shaped in cross section and is mounted on a driven shaft 31. This member is provided with one or more peripheral wiping portions or arms which are adapted to dip into the oil during .the rotation of the oiling member,

and also to contact at intervals with the thread and wipe the oil on the wiping arms tion illustrated.

indicated by. the that the portions of theouter wiping surface of the arms 32 contacting with the thread, moves contrary to the direction since it has been found th of movement of the thread at when the thread .and'wiper move in oppos'te directions while in contact, the oiling of more accurately regulate the thread can be d since the thread reference amount of oil or other liquid to does not tend to adhere to the wiper due to capillary action. The eripheral portions of the arms 32 of the wiper may be of any suitable or desired construction, those shown having their leading faces 33 eccentric with v to the axis of rotation of the wiper, and the outer ends of these eccentric faces'terminate in an abruptly inwardly extending curve 34,. for reasons which will be hereinafter explained. The shaft '31 is provided at one end thereof with suitable means for driving the same, p'ulleys 35 and 36 being shown in the construction illustrated which are secured to the shaft and which make it possible to drive the shaft at, different speeds for controlling the quantity of liquid to be supplied to the thread. It will be understood that during the operation of the machine both the spindle axis and the shaft 31- are operated at comparatively constant speed and the pulleys 35, 36 are only intended to be used for controllingithe total e applied to the thread.

In accordance with this invention, the thread is so guided relatively to the wiper member that is commenced and the speed thereof is relatively slow, the thread will be guided approximately as shown in Fig. 2, in which the wiper arms 32 will contact with the thread only during short arcs of their revolution, and when the speed of the thread has increased the thread will be guided as indicated in'Fig. 3. In this latter position the wiping portions of the arms 32 will engage with the thread during a much greater are of revolution, so that the thread will be in contact with the wiper for greaterlengths .of stretches thereof when the same moves at ahigher rate of speed.

In order to accomplish this operation, the 'threadguide 22, in the construction shown, is adjustable relatively to the wiper, the thread guide 22 being mounted on a slide member 37 which is slidably mounted on a guide arm 38 which may be rigidly secured on the tension device 2& or on any convenient stationary part of the machine. The slide 37 in the construction shown is in the form of a sleeve or collar extending around the guide arm 38" and is slidable lengthwise thereof. The guide arm is preferably also provided with a longitudinal slot 39 and a screw or bolt 40 on which the guide 22 is secured and which is secured to the slide member, passes through the slot and assists in guiding the slide member relatively to the guide arm, nuts of any suitable form being shown for removably securing the bolt 40 and the guide 22 carried thereby on the slide. The sleeve or slide member 37 is preferably provided with a laterally extending pin or trunnion 41. The movement of the thread guide 22 is controlled in accordance when the winding of the thread with the rate of lineal movement of the shown in Fig. 2, so that the threa thread, this being preferably accomplished by causing the t read guide 22 to move in accordance with the movement of the traverse frame 16'. To attain thls purpose an arm 43 mounted on and at an angle to the traverse frame 16 is rovided near the outer portion thereof wit a series of holes 44, arranged at different-distances from the axis 17 about which the traverse frame moves. A link connects at one end with any one of the holes 44 and at its other end 1s pivotall connected to the pin or trunnion of the sli e member 37. Consequently, as the traverse frame 16 swings about the axis 17 due to the accumulation of thread on the rotary support or spool X, the arm 43 and 1m 45 will move accordingly and Wlll move the slide member 37 and t downwardly.

The'link 45 is preferably ad ustable as to its length and for this purpose the link is made 'in two sections or parts connected by means of a turn buckle 46.

In the operation of the device for applying liquid to the thread, it will be obvious that when the parts are in the os1t1on proximately tangent to the outer portions of the wi er arms 32, only the tips of these arms wil touch the thread and through a comparatively short are of the revolution of the wiper. On the other hand when the thread is lowered as indicated in Fig. 3,

the thread will first contact with the camsurface 33 of each wiper arm 32 and thus receive a considerable .quantity of li uid from this cam surface, and then upon urther rotation of the wi er arm, the thread will wipe across theen 34 of the arm. It will also be obvious that when the thread is in the osition shown in Fig.3, the thread will be in contact with the surface of the wiper arm 32 during very much larfier'arcs of revolution of the arms than w en.the

arts are in the position shown in Fig. 2. gonsequently liquid is supplied'to reater length or stretch of the thread, whic compensates completely for the increase in speed of the t read. B means of the. construction described inc uding the uiding and tension devices a uniform app ication of oil or other liquid to the thread is insur'ed and the operation of the mechanism is entirely automatic and is controlled entirely by the outer diameter of the mass or bulk of thread which has been wound upon the rotary support or spool axis. By making the end portions 34 of the wiper arms of a fairly abrupt curvature, the arms when about to move out of engagement with the thread will contact with the thread only alon a small surface so that capillary attraction of the thread to the wiper will be negligibly small.

wiper 55, which is substantially 6 thread guide 22 is ap-' In the modified construction shown in Fig. 5, a substantiall cylindrical wiper member is employe in (place of the sha ed wiper illustrate an 3. The 0 eration of this device is similar to that which hasbeen described in that the thread guide 22 moves the thread into contact with a greater are of the surface of the c .lindrical member. In this construction, oweve'r the thread is continuously in contact with the wiper member 50 and in order to avoid supplying anexcess of liquid to the thread a stationary wiper'or brush 51 is preferably used to remove excess oil from the. rotary wipermembe'r 50.

Fig. 6 shows still another form of rotary elliptical in form and which contacts intermittently with the thread. In this case also the variationsin speed of the thread are compensated for by variations in the position of the thread uide 22. Other forms of rotary wi er mem ers may be employed if desired.
